Embodiment Construction

[0012] refer to figure 2 As shown, it is a hardware structure diagram of a preferred embodiment of the digital TV with Bluetooth dual-channel stereo in the present invention. The picture-in-picture digital TV includes an antenna 1 , a digital TV tuner 2 , a microprocessor 3 and a picture-in-picture processor 4 connected in series. The antenna 1 receives an external RF (Radio Frequency, radio frequency) digital TV signal and transmits it to a digital TV tuner 2 . The digital TV tuner 2 converts the received RF digital TV signal into a digital signal, and filters out the required digital TV signal and sends it to the microprocessor 3 . The microprocessor 3 converts the digital TV signal into a format recognizable by digital TV. The digital TV signal in this format includes sound and image, and then the microprocessor 3 transmits the converted digital TV signal to the picture-in-picture processor 4 . The picture-in-picture processor 4 extracts the video corresponding to the ch...

Abstract

The invention discloses a Bluetooth host-slave two sound track stereophony digital television comprising a host-slave picture processor, a first audio decoder and a second audio decoder; wherein the first audio decoder and the second audio decoder are respectively connected with the host-slave picture processor; the other end of the first audio decoder and the other end of the second audio decoder are respectively connected with a first Bluetooth transmitter and a second Bluetooth transmitter; when receiving two groups of audio data, the first audio decoder and the second audio decoder decodethe received two groups of received audio data and respectively transmit the decoded audio data to the first Bluetooth transmitter and the second Bluetooth transmitter; the first Bluetooth transmitter and the second Bluetooth transmitter convert the received decoded audio data to simulative signals to realize host-slave two sound track stereophony. Two-channel stereophony can be realized by usingthe invention so as to ensure the optimal sound effect.

Description

technical field [0001] The invention relates to a digital television with stereo two-channel, in particular to a digital television with two-channel bluetooth. Background technique [0002] With the improvement of living standards, people began to have higher and higher requirements for the quality of vision and hearing. And digital TV conforms to this requirement, so digital TV has been greatly promoted and popularized at present.
